compiler seems cannot find boost/shared_ptr.hpp - c++

Question

I am using Mac with OS 10.11.6
I am trying to install OpenGV on my Mac. This is a part of dependencies that will be needed to build the OpenSfM library. So, what I did is:
brew install homebrew/science/ceres-solver
brew install boost-python
brew install eigen
git clone https://github.com/paulinus/opengv.git
cd opengv
mkdir build
cd build
cmake .. -DBUILD_TESTS=OFF -DBUILD_PYTHON=ON
make install
But I got this error:
In file included from /Users/hilman_dayo/opengv/src/relative_pose/modules/main.cpp:47:
/Users/hilman_dayo/opengv/include/opengv/math/Sturm.hpp:43:10: fatal error: 'boost/shared_ptr.hpp' file not found
#include <boost/shared_ptr.hpp>
^
1 error generated.
make[2]: *** [CMakeFiles/opengv.dir/src/relative_pose/modules/main.o] Error 1
make[1]: *** [CMakeFiles/opengv.dir/all] Error 2
make: *** [all] Error 2
How can I solve this? Already checked, and the file is there at /usr/local/include/boost/shared_ptr.hpp.
If it is ever needed, this is the output during cmake:

Answer 1

OK. Comment by #usr1234567 give me a hint to find the answer. After a quick search, all I need to do is just execute this on the command line:
xcode-select --install
